In this example what we see is, if we use native function of quickdraw which sets pixels, it is going to be slower. The reason for this, we are using too muc...

Technical breakdown of low-level pixel manipulation using QuickDraw GWorld in C, featuring distance-based color calculations.

This algorithm adjusts the color saturation of an RGB color image in a similar manner as the color control on a color television. The algorithm is based upon...

A histogram shows how the 256 possible levels of brightness are distributed in an image. It could be compared to a horizontal line with 256 positions which r...

The edges of an image hold much of the information in that image. The edges tell where objects are, their shape and size, and something about their texture....

We are going to talk about geometrical transformations today. Before that we are checking out projects and how they are shaping before next week. Leif's sli...

Today we want to do couple of things. Title is image composition. We have been creating images from the stratch from thebeginning and then manipulated those ...
